When generating a cDNA library, one may get different sequences returned if samples are taken at different times. Why is this the case?
What will be an ideal response?
The cDNA library uses reverse transcriptase to copy mRNA present in the cell to DNA. If cellular conditions change over time the genes being expressed could change as well resulting in a change in the mRNA present when samples are taken. This would result in a different cDNA library being generated.
